Automatic water adding device for steam tank

Abstract

The invention discloses an automatic water adding device for a steam tank. The invention aims to provides an instrument which is capable of frequently keeping the rising and falling magnitude of the water level in the steam tank, namely water is added immediately when the water level is slightly decreased and the water is stopped from flowing when the water level is slightly increased. According to the technical scheme, the height of a water storage tank is greater than taht of the steam tank; the water storage tank is communicated with the steam tank through an air inlet pipe and a water conveying pipe, and the air inlet pipe is arranged above the water conveying pipe; an inlet of the air inlet pipe is located in the position, close to a water level in the steam tank, of the steam tank located in the lower side, and an outlet of the air inlet pipe is located in an upper space, above a water level, of the water storage tank; an inlet of the water conveying pipe is located in the water, below the water level, of the water storage tank, and an outlet of the water conveying pipe is located below the water level in the steam tank. According to the working principle, when the water level in the steam tank rises, the inlet of the air inlet pipe is submerged, and water flowing is stopped through vacuum formed in the water conveying process due to the fact that air or steam can not enter the sealed water storage tank; and when the water level in the steam tank falls, the inlet of the air inlet pipe is exposed, and the water supplying is resumed; the supping and stopping are conducted repeatedly and circularly.

Description

technical field [0001] The present invention relates to a device for automatically adding water to a steam tank, more precisely and more specifically, it is used to keep the water level in the steam tank always on the same plane, which is neither too high nor too low, that is, automatic filling when it is too low and automatic stop flow when it is too high a device. Background technique [0002] The steam tank or boiler is a water storage container used to make steam. When the water is heated and boiled and turned into steam, the steam keeps increasing and the water keeps decreasing. It must be added in time to avoid empty burning. When the amount is too small and the work is missed, if the amount is too much, the steam cannot be formed in a short time, so that there is a contradiction between supply and demand. Contents of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention aims to provide a steam tank in which the water lev...
